Docker
Cluster API requires that ClusterClasses referenced by a Cluster reside in the same namespace as the Cluster. To
create the necessary ClusterClass, run:
kubectl apply --server-side \
-f https://github.com/nutanix-cloud-native/cluster-api-runtime-extensions-nutanix/releases/download/v0.23.1/docker-cluster-class.yaml
You can then create your cluster. First, let's list the required variables:
clusterctl generate cluster my-cluster \
--from https://github.com/nutanix-cloud-native/cluster-api-runtime-extensions-nutanix/releases/download/v0.23.1/docker-cluster-cilium-helm-addon.yaml \
--list-variables
Export the required variables and any optional variables that you may want to set and then create your cluster:
clusterctl generate cluster my-cluster \
--from https://github.com/nutanix-cloud-native/cluster-api-runtime-extensions-nutanix/releases/download/v0.23.1/docker-cluster-cilium-helm-addon.yaml \
--kubernetes-version=v1.31.2 \
--worker-machine-count=1 \
| kubectl apply --server-side -f -
To customize your cluster configuration prior to creation, generate the cluster definition to a file and edit it before applying:
clusterctl generate cluster my-cluster \
--from https://github.com/nutanix-cloud-native/cluster-api-runtime-extensions-nutanix/releases/download/v0.23.1/docker-cluster-cilium-helm-addon.yaml \
--kubernetes-version=v1.31.2 >mycluster.yaml
# EDIT mycluster.yaml
kubectl apply --server-side -f mycluster.yaml
